VEHICLE-TIRE.

Application med september 11, 191s. serieu Ne. 119,380.

T0 all 'whom t may concern;

Be it known that I', CLAUDE SAFFoRD, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Vehicle- Tires, of which the following is a specification. l

My ,invention relates to-a vehicletire to be used on vehicles'of all kinds and classes, more particularly self-propelled vehicles, and the objects of my invention are: First, to provide a. tire of this class which is very durable; second, to provide a tire of this class which will not `puncture under ordi' nary circumstances; third, to provide a tire of this class the tread portion of whlch 1s sectional andl may be readily replaced where chipped, brokenor worn; fourth, to provide` a tire of this class which is simple, and economical of construction, durable and easy to install; fifth, to provide a tireof this class which affords practically the same pliability as the ordinary pneumatic tire,`and sixth, to provide a tire of this class which may be readily made applicable to the ldifferent and various rims of vehicles now in use belonging to the same class.

W'ith these and other objects` in view as will appear hereinafter my invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter described in detail and particularly set forth in the appended claim, reference being had to the accompanyingdrawings and to the characters of reference thereon which form a part of this specification, in which:

. Figure l is a sectional view of one side of my tire shown mounted on the rim. Fig. 2 is a perspective view of a fragmentary section of my tire mounted on the rim. Fig. 3 is a detailed plan view of a portion of the means for connecting the different sections to the pneumatic portion of the tire. Fig. 4 is a perspective view of the same. Fig. 5 is a perspective view of one of the clips for securing the connecting means to the pneumatic portion of the tire and Fig. 6 is a detailed side View of one of the tread sections. Similar characters of reference refer to similar parts throughout the several views. The rim 1, pneumatic casing 2, inner tube 3, tread sections 4, rollers 5, side links 6,

as shown is the ordinary or conventionall .type provided with beads 2a `around the inslde surface for holding said casing in said rim when the tube 3 inside of saidl casing is inflated. It will be here noted, however, that the rim and connection por-y tion of the casing2 may be any vof the various conventional types as desired. The

casing 2 consists of layers of fabric and rubber the same as the ordinary or conventional casing and is shaped similarly thereto except that on the outer surface are prosaid casing and the outer surface of the tire is provided with a flat surface against Vwhich the inner surfaces of the treadsecti`ons4 rest. These tread sections 4 are preferably of solid rubber lalthough they may be made of variousy kinds of material;

In some cases it might be desirable to make These tread sections are shaped as shown and areI them of metal and non-resilient.

each provided with oppositely dispose-d semi-circular recesses 4a so that when said sections are placed adjacent each other on the outer surface of the casing 2 a round hole is provided adapted to fit snugly the rollers 5 so that these sections are held in position by means of said rollers 5 which rollers are connected together by means of said links 6 which are provided with holes adapted to accommodate the bolt 7. It will be here noted that these bolts 7 are considerably smaller than the inside diameter of the rollers so as to allow considerable play relatively to said bolts so that the tread sections 4 may be moved inwardly some distance before the bolts 7 are moved. Mounted on each end of the bolts on the outside of the links 6 are the clips 8 which extend over the beads 2b for holding the sections 4 in certain relative position to the casing 2 and the side links 6 prevent expansion of the sections so that when the casing 2 is inflated, its outer surface' presses tightly against the inner sections, thus holding them in position by the friction of the surfaces; however,

the principal vided a. pair of beads 2b extending around easing depressed at the point pf ontact and if the Objectis 'sucently'large so that the play between the bolt 7 and the. rol'lrs is takenV up' then the side, 'links 'of the' Chain? are depressed and carried ailng' wthsad sections into 4the depressed portin o@ the casing 2.
